Orientation‐Dependent Arrangement of Antisite Defects in Lithium Iron(II) Phosphate Crystals

Aggregated antisite cations of iron (see picture, red) in the lithium sites of doped lithium iron phosphate (LiFePO4) are arranged preferentially along the b axis. To probe the peculiar array of the defects, Z-contrast STEM with a spherical-aberration correction is utilized. The images obtained using Z-contrast STEM suggest that the distribution of antisite defects in LiFePO4 can be adjusted for improved lithium ion transport.
